The human body is incredibly adaptive, able to train and improve in different energy systems, depending on the type of activity being performed. One such system that is fundamental to high-intensity exercises, such as sprinting, weightlifting, and explosive movements, is the anaerobic system. This system is responsible for fueling activities that demand short bursts of energy. It is essential for athletes or anyone seeking to improve performance in activities requiring strength, power, and endurance over a brief duration. How To Train Anaerobic System Effectively?
Training the anaerobic system is an often misunderstood aspect of fitness. However, through the proper combination of intensity, duration, and rest intervals, athletes can effectively improve their anaerobic performance. In this article, we will explore the fundamental concepts of the anaerobic system, its importance in physical fitness, and how to design an efficient anaerobic training program.
What Is the Anaerobic System?
The anaerobic system refers to the process of energy production that does not require oxygen. This is in contrast to the aerobic system, which uses oxygen to convert nutrients like carbohydrates and fats into energy. The anaerobic system comes into play during activities that are intense but of short duration, typically lasting from a few seconds up to about two minutes.
There are two primary anaerobic energy systems: the ATP-CP system (adenosine triphosphate-creatine phosphate system) and the anaerobic glycolysis system (also known as lactic acid system). Both play a crucial role in fueling high-intensity exercise.
1. ATP-CP System (Phosphagen System)
This system is the fastest to react and provides immediate energy for short bursts of maximal effort lasting approximately 10 seconds or less. The ATP-CP system uses stored adenosine triphosphate (ATP) and creatine phosphate (CP) within the muscles to provide this energy. It is used primarily in activities such as sprints, jumps, and heavy lifts.
2. Anaerobic Glycolysis (Lactic Acid System)
When exercise extends beyond 10 seconds and up to two minutes, the anaerobic glycolysis system kicks in. In this system, glucose is broken down into pyruvate to produce ATP. However, in the absence of oxygen, pyruvate is converted into lactate (lactic acid), leading to the accumulation of lactate in the muscles, which can cause fatigue. The anaerobic glycolysis system is engaged in activities like 400-meter sprints or high-intensity circuit training.
Why Train the Anaerobic System?
Training the anaerobic system is essential for improving athletic performance in various sports and fitness activities that require quick bursts of power or speed. The anaerobic energy system is used in activities like sprinting, swimming, wrestling, rowing, and weight training. Improving the anaerobic system increases power, explosiveness, and the ability to sustain high-intensity efforts.
Some benefits of anaerobic training include:
Increased Strength and Power: By focusing on the anaerobic system, athletes can enhance their ability to perform explosive movements, like lifting heavy weights or sprinting at top speeds.
Improved Muscle Endurance: Anaerobic training can enhance a muscle’s capacity to perform for extended periods before fatigue sets in.
Higher Lactate Threshold: Regular anaerobic training can increase the lactate threshold, allowing athletes to perform at higher intensities before fatigue and muscle burn set in.
Fat Loss: High-intensity anaerobic exercises, such as HIIT (High-Intensity Interval Training), can lead to increased calorie burn, fat loss, and improved metabolism.
Better Recovery: Training the anaerobic system also improves the body’s ability to recover from high-intensity efforts, leading to quicker recovery times between sets or between training sessions.
Key Principles for Training the Anaerobic System
To optimize anaerobic system training, it is important to follow certain principles and structure your workouts effectively. Below are some key principles:
1. Intensity
Anaerobic training requires high-intensity efforts to engage the anaerobic energy pathways. The exercise intensity should be near maximal effort (85-100% of your one-rep max or your fastest sprint pace). This level of intensity forces the body to rely on anaerobic energy systems, challenging the muscles and cardiovascular system.
2. Duration
Anaerobic efforts last anywhere from 5 to 90 seconds, depending on the type of exercise. For the ATP-CP system, short bursts of 5 to 10 seconds of maximum intensity are key. For the glycolytic system, 30 seconds to 90 seconds of high-intensity activity are ideal, after which fatigue starts to set in due to lactate accumulation.
3. Rest Intervals
One of the most important aspects of anaerobic training is rest. The body needs time to replenish the energy stores in the muscles (ATP and CP), especially for the ATP-CP system. Rest intervals between sets or exercises should be relatively long compared to aerobic training. Typically, rest intervals of 30 seconds to 5 minutes are used, depending on the workout’s focus. Longer rest periods are often incorporated for maximal strength training, while shorter rest periods are used in more anaerobic endurance-focused training.
4. Progressive Overload
Like any other form of exercise, the principle of progressive overload should be applied to anaerobic training. Gradually increasing the intensity, volume, or complexity of workouts will ensure that the body continues to adapt and improve. This could mean adding weight to a squat or increasing the intensity of a sprint interval workout.
Anaerobic Training Methods
There are several effective methods to train the anaerobic system, each targeting different aspects of anaerobic fitness. Below are some of the most popular methods:
1. High-Intensity Interval Training (HIIT)
HIIT is one of the most effective methods for training the anaerobic system. It involves alternating between short bursts of high-intensity activity and brief periods of rest or low-intensity recovery. The work-to-rest ratio can vary based on the goal, but typical ratios range from 1:1 to 1:3.
For example, a HIIT workout for anaerobic training might involve 30 seconds of sprinting followed by 90 seconds of walking or jogging, repeated for a total of 10 to 15 rounds.
Benefits of HIIT for Anaerobic Training:
- Increases VO2 max and lactate threshold.
- Improves both aerobic and anaerobic capacities.
- Burns fat effectively due to its intensity and afterburn effect (excess post-exercise oxygen consumption, or EPOC).
2. Sprint Interval Training (SIT)
SIT focuses specifically on improving the anaerobic system by performing repeated sprints over a short distance, typically 20 to 30 seconds in duration, followed by recovery periods. This type of training is beneficial for athletes in sports like soccer, football, and track and field, where speed and power are essential.
SIT Workout Example:
- Sprint for 20 seconds at full effort.
- Walk or jog for 1-2 minutes.
- Repeat for 10-15 rounds.
3. Plyometrics
Plyometric exercises, such as jump squats, box jumps, and burpees, are designed to increase explosive power and enhance the anaerobic system. These exercises rely on fast and explosive movements that demand a significant amount of energy from the muscles and nervous system. Plyometric training helps develop the ATP-CP system, improving strength and power for activities like jumping, sprinting, and rapid changes in direction.
Plyometric Workout Example:
- Jump squats: 3 sets of 8-12 reps.
- Box jumps: 3 sets of 6-10 reps.
- Lateral bounds: 3 sets of 10-12 reps.
4. Resistance Training
Resistance training is critical for developing strength, power, and muscle mass, all of which contribute to anaerobic performance. Heavy lifting with compound movements such as squats, deadlifts, and bench presses relies on the ATP-CP system for quick energy release. Short rest intervals between sets (30-90 seconds) can also help improve anaerobic endurance, specifically for the glycolytic system.
Resistance Training Example:
- Deadlift: 4 sets of 5 reps (85-90% of 1RM).
- Bench press: 4 sets of 5-8 reps.
- Squat: 4 sets of 6-8 reps.
Program Design for Anaerobic Training
When designing an anaerobic training program, it is important to focus on the key components of intensity, duration, and recovery. Here’s a sample program that combines different anaerobic training methods:
